LOGGING DEVICE.

Application filed December 27, 1921.

To all whom it may concern:

Be it known that I, DANIEL W. GLAsoooK, a citizen of the United States,residing at the city of Stockton, county of San Joaquin, and State ofCalifornia, have invented new and useful Improvements in LoggingDevices, of which the following is a specification.

This invention relates to a logging device and has particular referenceto a low tractor logging wheel device equipped with novel means forlifting and holding logs of varying diameters.

The primary object of this invention is to provide a device of thecharacter described so constructed as to operate in confined places oron rough hilly ground whereby I attain high clearance on a low axleconstruction.

An additional object is to provide a novel type of main frame adapted tosupport the axles of the device with the axle so supported from bothsides that the danger of the axle breaking is reduced to a minimum.

A furtherv object of this invention is to provide a device of thecharacter described, which is comparatively simple in construction,inexpensive to manufacture, positive in action and highly serviceableand efficient in use.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification, andin which like characters are employed to designate like parts throughoutthe same Fig. 1 is a side of my tractor logging wheeled device.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a top plan view of the device.

Fig. 4 is a sectional View on line YY of Fig. 3.

.Among other elements my improvement comprises a tongue A, arrangedbetween inner rearwardly extending rods B and outer rearwardly anddownwardly extending rods B each of the said rods comprising threadedsections as illustrated joined by a turnbuckle B. The outer downwardlyand rearwardly extending rods B afford bearings M for the outer ends ofthe axles P of wheels O.

The main frame of the machine is made preferably of structural steel andincludes Serial No. 525,202.

a beam D to which the rear ends of the inner rods B are connected asshown in Figures 1 and 3. Sand frame also includes two plates R, fixedto said beam D, forming an arch and trussmg the mam frame and affordingbearings for the inner ends of the axles P, as shown 1n Flg. 2.

These plates R are spaced apart the proper distance to allow a liftingchain S to pass freely up and down through guides T at the lower ends ofthe plates R. Said guides serve to receive and maintain in spacedrelation the pendent portions of the chain S, and thereby operate tokeep the. chain in place, and also to provide means for fastening theaxles P at or near the lower ends of the plates R as shown in Fig. 2.

On the ends of the beam D are pendent brackets B extending down to andreceiv ing the outer portions of the axles P to rigidly support the sameas shown in Fig. 2.

Fixed to and extending forwardly from the beam D are hounds J whichserve to brace and lend increased strength to the main frame. Thesehounds are fixedly connected at their forward ends to a cross member 20which cross member forms a guide 21 for the tongue A as shown in Figure4 and also serves for the connection of the forward ends of the rods Band B. In virtue of the said rodsv including turnbuckles B as described,the machine may be adjusted to any position forward or back, so as tobalance the load for any height of tractor.

On the top of the beam D are six bracket bearings, the inner bearings Ghaving antifriction rollers G" placed at such a position as to allow thetongue A (see Fig. 1) to pass through under them freely. Carried by thebeam D and disposed under the tongue A is an anti-friction roller D.(See dotted lines in Figure 2.)

Journaled in the bearings G is a shaft H with a spur gear I keyed orfastened in its center as shown in Fig. 2.

On top of the hitch tongue A is a rack A with teeth engaging with thegear I, as shown in Fig. 1, the object of the same being that when thetractor moves forward the rack on the hitch tongue A (Fig. 1) will alsomove forward, causing the gear to rotate turning the shaft, thus windingthe chain, which is arranged to wind up on said shaft, causing the logsaround which the chain has been locked, to be lifted from the ground asshown in Fig. 2.

Carried by a rear pendent portion 30 on the tongue A is a buffer 31,opposed to the rear side of the beam D and yieldingly maintained in theposition illustrated through the mediumof a coil spring 32 mounted onthe buffer and interposed between the said rear portion 30 and the heador forward enlargement of the buffer. Manifestly the said buffer willserve on forward movement of the tongue A relative to the main frame ofthe apparatus to bring up against the rear side of the beam D andthereby absorb shock and ar.

From the foregoing description considered in connection with theaccompanying drawings, it will be evident that I have de vised a highlyefficient device that will serve to lift and hold a plurality of logs ofvarying diameters.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having described my invention, what I claim and desire to secure byLetters-Patent,
